If you add a proton neutron and electron to an atom explain why the atom would not be the same element?

Answer 1

BECAUSE ON ADDING ANYTHING (PROTON, NEUTRON OR ELECTRON) THE CHEMICAL PROPERTIES OF THE ATOM DOES NOT REMAIN THE SAME.

1. AS ON ADDING ELECTRON THE ATOM WILL BE IONIZED AND WILL BECOME MORE NEGATIVELY CHARGED AND THUS WILL REACT WITH DIFFERENT ELEMENT IN A DIFFERENT MANNER OR FORM DIFFERENT CHEMICAL FORMULAS. FOR EXAMPLE: C + O2 = CO2 BUT IF WE ADD 2 MORE ELECTRONS TO OXYGEN THE IT WILL FORM CO.

2. THE Atomic Mass OF A HYDROGEN ATOM IS 1 BECAUSE IT ONLY CONTAIN 1 PROTON (i.e. NO NEUTRON) BUT IF WE ADD I NEUTRON TO IT ITS ATOMIC MASS WILL BE 2 WHICH IS THE ATOMIC PASS OF A DIFFERENT ELEMENT DEUTRIUM AND THUS THE ELEMENT WILL NOT REMAIN THE SAME.(not sure of the spelling & grammar.)

(ii)THE ATOMIC MASS OF URANIUM'S STABLE ISOTOPE IS 238. IF WE ADD A NEUTRON ITS ATOMIC MASS WILL BECOME 239 WHICH IS THE ATOMIC MASS OF POLONIUM AND THUS THE ELEMENT WILL NOT REMAIN SAME.

3. IF WE ADD PROTON TO AN ATOM ITS ATOMIC NUMBER WILL CHANGED AND THUS IT CHEMICAL PROPERTIES WILL ALSO BE CHANGED.

Answer 2

An element is defined as all of the isotopes having the same number of protons. Changing the number of protons changes the element to a different element. If you just changed the number of neutrons and/or electrons, it would still be the same element.

Answer 3

Adding a proton would change the atomic number, making it a different element. Neutrons do not affect the element's identity. Adding an electron would create an ion of the element but not change its identity.
